I removed the top cover and found the left main suspension spring broken. Appliance Part Pros had the new springs (2 I replaced both) at my door in 26 hours. Excellent service from this company.
After disassembling the drum from the chassis of the machine, it was very easy to replace the springs.
i do wish however that I had purchased a higher quality machine. LG refused to do anything to help and the machine is only 3 years old and gets minimal use.
Hats off however to Appliance Parts Pros. You have earned your name.
